The AMS Seal of Approval is a discontinued credential that does not require a bachelor's or higher degree in atmospheric science or meteorology to attain it.
Note that while Sussman states that he attended the University of Missouri, it is unclear if he completed the degree.
Brian Sussman is a meteorologist and radio and television weatherman. He works in conservative talk radio at San Francisco’s KSFO-AM, a position he has used to express his views on climate change. Apart from being the regular feature of KSFO's Right Thinking from the Left Coast, he hosts his own The Brian Sussman Show, on KSFO weekdays from 6 p.m. to 8 p.m. PT.
Stance on Climate Change
“For many decades, communists, socialists and the global elite have tossed a dizzying array of predicaments into American culture; that carbon dioxide emissions generated by mankind are ruining the planet, is their greatest assertion yet.” 
Sussman has claimed that “… the temperature record of the earth is clearly rigged.” 
“All one needs to see through the global warming scam is a rudimentary understanding of science, a decent grasp of mathematics, respect for the scientific method, and the willingness to engage in a little research. Together, those attributes will allow anyone to see that the theory of anthropogenic global warming is about as sturdy as a two-legged stool.” 
“EARTH DAY DENIGRATES CAPITALISM, AND MAN On this date in 1970, a trio of radical dreamers established Earth Day, an annual event designed to assault capitalism, free markets, and mankind.” 
Regarding the victims of Hurricane Katrina, although he admitted he was starting to sound “callous,” he said “you shouldn't put the military or the national guard in danger because some knuckelheads didn't decide to evacuate.” 
“The most amazing thing were my encounters with the absolute fools who are following global warming’s poster boy, Al Gore. They clearly don’t know how to think for themselves. I’m sure if they would honestly and openly read my book, they would realize they are being totally played.” 
MediaMatters has another list of Sussman's quotes.

DeSmogBlog researched the co-sponsors behind Heartland's ICCC7 and found that they had collectively received over $67 million from ExxonMobil, the Koch Brothers and the conservative Scaife family foundations.
Heartland's president Joe Bast revealed at the end of the conference that the Institute has no plans for future ICCCs. This could be in part due to the defections of corporate sponsors following Heartland's unsuccessful Unabomber billboard campaign and the unintended release of their confidential documents.
